The Nature Loo™ Alectura Premium system is a specialized design for tiny homes with a low underfloor clearance requirement of 500 mm, making it very suitable for transportable housing and most retro installations. This composting toilet model is suitable for a couple looking to install a composting toilet in their tiny house.

The Clivus Multrum™ CM HP system is designing to meet the larger capacity requirement of a few users to a family unit with a chamber (tank) underfloor-clearance requirement of 750mm

The Compact is an elegant low-profile unit with the looks to complement any bathroom. Sun-Mar engineers designed this low-profile toilet by developing and patenting a new variable diameter Bio-drum which is small at the front and large at the rear. To maintain the uninterrupted lines of the Compact, a patented Bio-drum handle recesses into the body of the unit to mix and aerate the compost.

If you’re in a situation where you need to be off-the-grid and completely self-sufficient, then this is the Sun-Mar model you want to look at. The Excel NE model was first designed in 1981 and still today it remains the standard-setting unit for completely non-electric composting toilets.

The Excel is the best-selling unit in North America and for good reason. It is a high-capacity Bio-drum toilet that is very simple to operate, features well-proven technology, and is extremely reliable. The Excel was the first ever self-contained composting toilet to be certified by the National Sanitation Foundation (NSF). So, when you purchase an Excel, you are literally purchasing a composting toilet that sets the standard.

Designed for 1 person full-time and up to 3 people part-time, Sun-Mar Spacesaver 240 is a compact composting toilet made for small spaces. Spacesaver 240 is a fantastic choice for baches, sleep-outs, cabins, or any location where there is access to a reliable power supply.
